Visible and near infrared reflectance spectroscopy was used to predict pH at 24h (pH24) post-mortem, sarcomere length (SL), cooking loss (CL), Warner-Bratzler Shear Force (WBSF) and colour parameters (L(∗), a(∗), b(∗)) in beef cattle samples. Samples from M. longissimus thoracis et lumborum from 30 bulls were aged at 4°C for 1, 3, 7 and 14 days and analysed for pH, SL, CL, WBSF and colour. NIRS...

This paper outlines the process of colour matching stereo pairs of images using a disparity map as input along with the original images. We describe the functionality of a plugin developed for Nuke, which we call Eyematch, that performs this automatic colour matching under conditions set by the user. The user is presented with various parameters to fine tune the matching process, but no prior k...

Ethephon sprayed directly onto pepino fruits (Solanum muricatum Ait., Chilean clone CH8) at 1920 mg lÿ1 advanced colour changes and therefore earliness of the crop. Colour changes evaluated with a HunterLab colorimeter occurred more quickly in ethephon-treated fruits in which a*/b* ratio changed soon after treatment and reached the highest values in treated fruits. Among four visually classifie...

Bound-state corrections to J/ψ production from almost real photons are calculated in the colour-singlet model. A systematic, gauge-invariant, theory of hard quarkonium processes is used upto O(v2), where v is the relative velocity of the quarks. The internal structure of the meson is characterised by two parameters, ǫB/M and ∇2φ(0)/M2φ(0), in addition to the usual wavefunction at the origin φ(0...

In this paper, an overview of Doppler ultrasound quality assurance (QA) testing will be presented in three sections. The first section will review the different Doppler ultrasound parameters recommended by professional bodies for use in QA protocols. The second section will include an evaluation and critique of the main test devices used to assess Doppler performance, while the final section of...

Context. The structural parameters of the disk of the Large Magellanic Cloud (LMC) are estimated. Aims. We used the JH photometric data of red clump (RC) stars from the Magellanic Cloud Point Source Catalog (MCPSC) obtained from the InfraRed Survey Facility (IRSF) to estimate the structural parameters of the LMC disk, such as the inclination, i, and the position angle of the line of nodes (PAlo...

The perceptual correlate to hue and the stability of its representation in the coordinates of Logvinenko's illumination-invariant object-colour atlas (Logvinenko, 2009) are investigated. Logvinenko's object-colour atlas represents the colours of objects in terms of special rectangular reflectance functions defined by 3-parameters, a (chromatic purity), o (spectral bandwidth) and A. (central wav...

Copigmentation has been suggested as a main colour stabilising mechanism in plants protecting the coloured flavylium cation from the nucleophilic attack by the water molecule. In this study influence of phenolic compounds addition (catechol, 4-methyl catechol, (+)-catechin and gallic acid) on stability of red currant juice anthocyanins (copigment:pigment molar ratio 50:1 and 100:1) during 30 da...

A method based on colour information is proposed to detect defects on ‘Golden Delicious’ apples. In a first step, a colour model based on the variability of the normal colour is described. To segment the defects, each pixel of an apple image is compared with the model. If it matches the pixel, it is considered as belonging to healthy tissue, otherwise as a defect. Two other steps refine the seg...
